Do-It-yourself Wood Roasting
Firing wood is one of the simplest ways to decorate and protect a surface from a number of harmful effects. How to do such an operation at home is step by step described in the article.For large-scale works, it is better to get a large gas burner, which is designed for laying a bitumen roof. In addition to a source of directional fire, you will also need felt. In the extreme case, you can take a washcloth from the kitchen and apply a more rigid side to it. In fact, this is all you need.In the photo you can clearly see such places. As a rule, they appear on the knots, and after the first pass they do not darken, but become covered with boiling resin. It is easily flammable and can ruin the entire result, because the knots should be warmed up carefully. Warmed, waited until boils, then again. Repeat until boiling stops.While the resin boils and the wood in these places cools down, the second stage is performed in parallel - deep firing. The challenge is to make the surface char and crack slightly. The photo below clearly shows how it looks.The next stage - cleaning the surface of soot.You can do this in several ways: with felt, a soft brush or a special brush for a grinder (brush for brashing). The only condition for all cases is that it is necessary to scrub soot only in the direction of the wood fibers. Sandpaper is not suitable for these purposes. It is advisable to use it only when the surface firing of wood. In this case, it is necessary to remove all burnt soft fibers, and sandpaper without scratches will not cope with this task.By the way, if you want the result to be lighter than in the pictures, the surface should be brushed longer. But to achieve lighter shades can only brush. Felt "get" to the light wood will not work. Some masters wash away soot with water, which, in principle, gives a good result. But it should be borne in mind that dry wood with direct contact with water will take a little moisture on itself, which, in turn, can lead to deformations and other problems in the future.A more predictable result is obtained only on a dry one. After firing, it remains only to cover the wood with a protective compound. To get a silky, matte surface that feels like a pure tree - use special oils. Glossy surface, iridescent under the sun's rays and from different angles of vision from black to light - is obtained after applying several layers of conventional wood varnish.
Who thought up to burn wood?According to one of the versions, it is considered that the Japanese began to burn wood first. In this case, they used this technology, oddly enough, not on their products. Initially, in this way they saved the forest from fire in the season of fires. The burnt lower part of the trunk became highly inflammable and, accordingly, was less exposed to fire. The second popular legend also hails from Japan. If you believe this version, then once the Japanese noticed that after a fire in the forest, charred trunks lasted longer than those that had passed the fire. In particular, they noted for themselves that the burnt wood does not rot so quickly, and also insects do not sharpen it at all. Later, this technology, prompted to people by nature itself, began to be used in construction.So, before installation, the roofing board, wall beams, wooden piles were burned. This made the building more durable, protected from insects and, in part, from fire. Even later, they began to use firing for decorating wood products, in particular, for furniture that is operated outdoors. The goal, in this case, was not only protecting the material from harmful effects, but also giving the surface an attractive appearance. There is also a version that it was the Vikings who began to burn wood long before the Japanese. They used this technology to process their ships.
The advantages of burnt woodThe advantages of wood treated with open fire are:
- presentable appearance;
- non-attractiveness for insects;
- increased fire resistance;
- compacted surface;
- increased strength;
- improved moisture resistance;
- protection from ultraviolet radiation.
Home technology applicationIn everyday life, kiln lumber is used everywhere. The technology allows without the use of stains, toners and oils to turn pine into wood of rare species. In particular, during deep firing, which is described in this article, the most defective pine easily turns into wenge (it grows mainly in Africa). It is especially useful to use firing in the manufacture of products and structures that will be used outdoors. This may be garden furniture, fence, arbor. Also, fire often handles wooden elements of the house - cladding, frontal boards, terraces, balusters of stairs, etc. The burned wooden caskets, gift cases, picture frames, grooves and photographs, various stands and lamps look beautiful.
What kind of wood can be burned?Not all wood can be protected and decorated in this way. First of all, it concerns fruit breeds, an oak, an ash-tree and an alder. However, the most common lumber - pine and fir - tree burns perfectly.You can also use veneer and multilayered plywood using fire. During processing, soft wood will burn out and remove, and solid fibers will stand out in a darker color. At the same time, knots, blue, fungus and other defects are not a problem for fire. When firing coniferous wood, it is better to take dried material. It burns much faster, there is less tar in it, which will later be certain problems. Raw wood is also quite possible to burn. However, it should be borne in mind that such processing will partially clog the pores of the material, and the moisture remaining inside will go out much longer, which is not good.
Tools and materials for firingThe main tool in this matter - gas-burner. Just an open fire (gas stove, fire, etc.) does not fit well, and even a large surface will not burn evenly. Also it is undesirable to use a blowtorch on gasoline. It burns, of course, excellently, but drops of unburned fuel can fly out of its nozzle, leaving glossy spots on wood.Alternatively, you can try to use a building dryer. But it takes a long time with it, and it will not be possible to achieve a deep roasting. The gas burner for this business fits the best. It's worth a penny, it's safe to use, easy to monitor and customize. You can even get by with the cheapest Chinese-made version, which, together with a gas canister, will cost about $ 5.
Step-by-step wood firing. The nuances of technology.Deep firing should begin with a surface passage of the burner for the material. At this stage, it is necessary to warm the wood evenly, burn out the protruding pile, and also to open the places where the resin is concentrated in large quantities.These sites will need to pay special attention later.
ResultsIn general, decorating the simplest pine with roasting is not a complicated procedure, requiring expertise, expensive tools and compounds . The main thing is to prevent long-term burning of wood, completely evaporate the resin, achieve cracking and remove soot only in the direction of the fibers.
